Here is an HOA lawn maintenance letter template.
To,
Mr. [name]
Address: ______.
This letter is a soft reminder that as a part of [name of] Homeowners association, it is your responsibility to maintain your lawn in excellent condition. The exterior of your house has a great impact on the overall scenery of the neighbourhood. If you ignore your yard, it will not remain aesthetically appealing for other members of the HOA. For further details, study the Covenants, Conditions and Restrictions (CC&R) section about lawn maintenance.
Thank You,
[Name of the board member],
Disciplinary Committee [name of] HOA board.
